On the Behaviour of Asymmetric Cylindrical Gears in Gear Transmissions
2012Asymmetric gears have been proposed more than twenty years ago as the ultimate solution to increase the load capacity of gear drives while reducing their weight and dimensions. However, there are apparently contradictive statements in the literature regarding whether the higher pressure angle should be applied to the driving or coast side of the gear ...

Probabilistic Analysis of MEMS Asymmetric Gear Tooth
Design Engineering and Computers and Information in Engineering, Parts A and B, 2006Asymmetric gear teeth are used to improve the performance of gears by increasing the load capacity or by reducing vibrations. Recently these types of gears have found application in MEMS devices where the use of gears is on the rise. In this research a probabilistic computer program, in conjunction with a commercially available finite element program ...

Direct Gear Design for Asymmetric Tooth Gears
2015In many gear drives, the tooth load on one flank is significantly higher and is applied for longer periods of time than for the opposite one. An asymmetric tooth shape reflects this functional difference. Design intent of asymmetric gear teeth is to improve performance of the primary drive profiles at the expense of the performance off the opposite ...

“Asymmetric gear wheel: thermographic analysis”
2004We have studied an experimental system designed to measure the state of stress existing inside asymmetric gear wheels under load. Such experimental system consists of a test bench which constrains the two asymmetric gear wheels at the operating centre distance; a load is applied in order to simulate the cosntraint during operation.

Asymmetric Gear Noise Sidebands and Application to Planetary Gear Noise Reduction
SAE Technical Paper Series, 2005<div class="htmlview paragraph">Asymmetric sidebands of gear noise are frequently observed with a planetary gear set, and are different from typical sidebands that are symmetrical around the gear mesh order (or mesh frequency). The asymmetric sidebands are found to be caused by phase differences between the different mesh points.

Asymmetric Gears: Parameter Selection Approach
Applied Mechanics and Materials, 2011In many gear transmissions the tooth load on one flank is significantly higher and is applied for longer periods of time than for the opposite one. An asymmetric tooth shape reflects this functional difference. This paper describes an approach to rationalize the asymmetric gears parameter selection to meet a variety of operating conditions and ...

Terminology and Design of Asymmetrical Gears for Aircraft
2015Main calculation principle of gear wheel geometry with asymmetrical tooth profile is presented. The paper presents calculation of bending stresses by means of YFS coefficient which takes into account the tooth shape and stress concentration. Graphic method of YFS coefficients calculation is described.

Design and Analysis of Asymmetrical Spur Gear Drive for Automobile Gear Box Application
Applied Mechanics and Materials, 2014This work mainly aims to explore the actual load, fillet and contact stresses induced during a mesh cycle in a spur gear tooth. As the mesh stiffness differs at different contact points along the path of contact, it significantly affects the load sharing between the simultaneously meshed contact pairs hence stresses.

Application, synthesis, and manufacture of involute gear transmissions with asymmetric gear profiles
Russian Engineering Research, 2009By investigating possible applications of involute gear transmissions with asymmetric gear profiles, three levels of transmissions may be identified. Each level is characterized by a particular set of engagement angles, operational parameters, types of gear, and manufacturing methods.
